Where is the air intake for the heating system in a 1999 camry? Also I'm getting mice in my car I was wondering if there was anywhere else they could get in because I want to block those areas off with screen.

 

There are two intake locations. One in front of the windshield for fresh air. The other under the dash for bypass air. There are also air exhaust outlets under the front seats which are not protected as the dash outlets.

Mice can enter the bypass vents and the outlet under the seats.

Look under the passengers side of the dash for the round blower motor body. The vents are on the box above the blower motor. Look under the front seats for the outlets.

If you have mice also check for debris in the engine filter box.

 

I blocked the vents under the seats and they still get in, I'll try blocking the vents near the blower moter. Will blocking the blower moter vents prevent me from using the heat or ac?

 

Are the bypass vents the vents that are right on top of the blower moter?

 

Look on the passengers side above the blower motor.

Don't block, use a screen course enough to block mice. I have used 1/2 screen, hot melt glued to the case and vents.

If the bypass vent is blocked the recirc air will be blocked.

 

Alright I glued some screen over the intake holes hopefully it stops them.

 

Great!
